No, not really

As much fun as I have a/ my Tamzooka, I know it is soft at 450mm plus -

Someday I will rent such a thing and still not buy it. If I was making my living from image capture sure, but not now.

That and it would take about 3 or 4 weeks before I would be able to get anything to focus..... once the swelling has gone down from around my eyes from my wife beating me.
